Lung cancer There are two main types of lung cancer: Small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). Lung cancer is more commonly found in men than in women, but is the number one cause of cancer deaths in both genders worldwide. The risk of developing lung cancer increases with age. If the cancer is an advanced stage the general prognosis is poor.
Signs and symptoms of lung cancer may include one or more of the following:
- Persistent cough
- Shortness of breath
- Pain in the chest, shoulder, or back unrelated to pain from coughing
Lung cancer is most highly associated with the smoking and inhaling carcinogens found in tobacco, either by active use or through secondhand smoke. Other potential risk factors may include exposure to certain chemicals, radiation exposure, air pollution, genetic predisposition, and abnormalities in or damage to the body’s immune system.
Treatment options typically depend on the type and stage of the lung cancer, but may include one or more of the following:
- Radiation therapy
- Targeted therapy
